for definitions of {it:clockpos} and {it:ringpos}.


{title:Description}

{p 4 4 2}
{cmd:graph} {cmd:combine} arrays separately drawn graphs into one graph and
shows a single common legend taken from one of the graphs.


{title:Options}

{p 4 8 2}
{cmd:legendfrom(}{it:name}{cmd:)} specifies the graph from which the legend for
   the combined graphs is to be taken, the default is the first graph in the
   list.  The argument {it:name} must match one of the names from the list of 
   graph names specified.

{p 4 8 2}
{cmd:position(}{it:clockpos}{cmd:)} and
{cmd:ring(}{it:ringpos}{cmd:)}
    override the default location of the legend, which is usually centered
    below the plot region.  {cmd:position()} specifies a direction {it:(sic)}
    according to the hours on the dial of a 12-hour clock, and {cmd:ring()}
    specifies the distance from the plot region.

{p 8 8 2}
    {cmd:ring(0)} is defined as being inside the plot region itself and allows you
    to place the legend inside the plot.  {cmd:ring(}{it:k}{cmd:)}, {it:k}>0,
    specifies positions outside the plot region; the larger the {cmd:ring()}
    value, the farther away from the plot region is the legend.  {cmd:ring()}
    values may be integers or nonintegers and are treated ordinally.

{p 8 8 2}
    {cmd:position(12)} puts the legend directly above the plot region
    (assuming {cmd:ring()}>0), {cmd:position(3)} directly to the right
    of the plot region, and so on.

{p 8 8 2}
    See
    {hi:Where legends appear} under {hi:Remarks} below and see
    {hi:Positioning of titles} in
    {it:{help title_options}} for more information on
    the {cmd:position()} and {cmd:ring()} suboptions.

{p 4 8 2}
{cmd:span} specifies that the legend is to be placed in an area spanning the
    entire width (or height) of the graph rather than an area spanning the
    plot region.
    This affects whether the legend is centered with respect to the plot
    region or the entire graph.
    See {hi:Spanning} in
    {it:{help title_options}} for more information on {cmd:span}.

{p 4 8 2}
{it:combine_options} specify how the graphs are combined, titling the combined
    graphs, and other common graph options.  See 
    {help graph_combine} for details.


{title:Remarks}


{p 4 4 2}
{cmd:grc1leg} is the same as {cmd:graph combine} except that it displays a
single common legend for all of the combined graphs.  This legend is one of
the legends from the graphs being combined, .  Otherwise, {cmd:grc1leg} is
exactly like {cmd:graph combine}, see {help graph_combine} for further
remarks.
